Providence, R. Island 1., a corporation of Rhode Claims. (Cl. 88-182)This invention relates to a camera, and more particularly to anautomatic camera so designed that it will take exposures of successivearticles to be photographed, position the articles for ex- 5 posure,remove them after exposure, and replace the exposed sensitized materialby fresh unexposed sensitized material, all automatically and withoutattention of the operator otherwise than to feed the articles to beexposed to the machine.

An object of the invention is the provision of such a machine which islight, compact, simple to operate, and which is generally improved andmore satisfactory than other machines heretofore known.

Another object of the invention is the provision of a machine especiallydesigned and adapted for the rapid reproduction of relatively smallforms such as cards and the like.

Still another object is the provision of simple and improved means forfeeding sensitized sheet material automatically after each exposure,which means is capable of easy and precise ad- 'justment.

A further object is the provision of improved means for holding thesensitized material in the focal plane of the camera, which means is sodesigned that the sensitized material may be conveniently threadedthrough the holding means.

A still further object of the invention is the provision of varioussimplified and improved details of construction, many of which areapplicable to various cameras of other types.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims atthe endof the specification.

This application is a division of our copending application for patentfor Camera, Serial No. 582,361, filed December 21, 1931.

Referring now to Figs. 1 to 4 inclusive, the machine comprises a mainbody or casing 50 having near its bottom a forward extension 5| runningsubstantially the whole length of the casing, and an upward extension 52near the right hand end of the main casing 50.

The focal plane support, the supply of sensi tized material, theshutter, and the lens are mounted either in or upon the casing portion52, which may be said to constitute the camera proper. The drivingmechanism for the camera is located primarily within the main casingportion 50 and the forward extension 5|. Above this extension 5i andmounted thereon is a casing 53 containing a copy conveyor forautomatically moving the articles to be photographed into thephotographic field of the camera, bringing them to rest in this fieldwhile'one or more exposures are made, and then removing them from thefield. 7

It will be most convenient to describe first the parts of the cameraproper. Referring now especially to Fig. 5 of the drawings, the portion52 of the casing is provided with a horizontal partition 55 serving as afloor for supporting a roll box 55 insertable in and removable from thecasing through a rear door 51. The roll box 55 is guided laterally bysuitable guide means, such as the angle irons 58, and-it carries a roll59 of sensitized photographic material such as paper, which may be ledfrom the roll 59 over a guide roller 60 and thence downwardly over afocal plane support, the strip of sensitized material at this pointbeing indicated by the letter P.

The focal plane support, best shown in Figs. 5 to 7 inclusive, comprisesa vertical frame member 6| having a large central aperture therein, towhich frame member BI is secured a supplementary frame member 62 servingto hold a ground glass plate 63 in predetermined vertical positionwithin the aperture of the frame 6|. The sensitized material Ppassesdownwardly over the front of the frame 6| and of the ground glass plate63. When the sensitized material and the roll box are removed from thecamera and the rear door 57 is opened, the camera may .be focused byobserving the image on the ground glass plate 63.

The frame 6| on its front side is provided with rabbets and with plates64, which together form guideways in which a'masking and retaining plate65 is vertically slidable. This plate has a bent over fiange 56 at itstop which may be conveniently grasped when a top door 61 of the casingis opened, so that the plate 65 may be removed from its guideways by avertical upward movement or replaced in its guideways by a verticaldownward movement. When in position in its guideways, the plate 65serves to retain the sensitized material P accurately and smoothlyagainst the focal plane support 63, thus maintaining it accurately inthe focal plane. The plate 65 is provided with an aperture 68 definingthe exposure area of the sensitized material and determining the size ofthe exposure made thereon, the rest of the material being masked off bythe plate 65 which is preferably of metal or other opaque material.-Thus the plate 65 prevents stray light from affecting any part of thesensitized material, except that part which it is desired to expose.

After passing over the focal plane support the sensitized materialcontinues downwardly through an aperture 10 in the partition 55 andthrough a short chute II and between two feeding rolls l2 and 13, theformer fixed to a shaft I4 rotatable in bearings fixed-in the casing,while the latter is mounted on a shaft 15, the ends of which arerotatably mounted in a pair of upstanding arms I6 pivoted at 11 at theirlower ends and urged rearwardly by springs 18 so that the roller I3normally tends to hold the sensitized material firmly against the roller12. The upper ends of the gm l6 engage in notches in a. cross shaft 19which niay be oscillated from outside the casing by a handle (Fig. 2),so that the arms I6 are cammed forwardly to separate the roller 13 fromroller 12 and allow sensitized material to be inserted between therollers.

Passing on downwardly beyond the feeding rollers, the exposed sensitizedmaterial is wound up on a rewinding reel mounted in the manner bestshown in Fig. 2. A shaft 86 is mounted in ball bearings 81 and carries apulley 88 having pins 89 projecting from the side thereof. These pinsengage in corresponding recesses in one end of the rewinding reel 85 sothat motion transmitted to the pulley 88 as hereafter described will beimparted to the reel 85 and will cause the sensitized material to bewound up on this reel. The opposite end of the rewinding reel is held ona shaft 90 inwardly urged by a spring 9| into a central aperture in therewinding reel, but

which may be pulled rightwardly to release the rewinding reel bygrasping the external handle 92. When a reel 85 becomes filled withexposed sensitized material, it may be removed from the machine througha suitable door in the casing and an empty reel may be substituted foraccumulating further exposed material.

The camera front, best illustrated in Figs. 2, 4, and '7, comprises acasing I00 seated in a suitable socket in the front of the camera casing52 and held therein by a fixed overlying holding plate IOI at the righthand side and a movable overlying holding plate I02 at the left handside. The plate I02 is held in place by screws passing through obliqueslots, as best shown in Fig. 2, so that by lifting upwardly on the plateI02, it will at the same time move outwardly and release the lefthandedge of the casing IOI, so that this casing may be readily detached.

At the front of the casing I M is a split ring and clamping screw I03for detachably holding a suitable lens and prism unit I 04, the prismbeing provided as is usual in commercial cameras for bending light raysthrough substantially a right angle, so that articles to be photographedmay be laid in substantially horizontal position beneath the prism'andthe light rays passing upwardly therefrom will be bent to pass throughthe lens and into the camera.

On the front of the casing I00 is a knob I06 fixed to the front end ofthe shaft I 01 which carries at its rear end an arm I08 (Figs. '7 and8), supporting a color filter I00 which may be held in elevatedineffective position by a leaf spring IIO. By oscillating the knob I 06in one direction or the other, the color filter I09 can be oscillateddownwardly into an effective position in the optical axis of the camera,or moved upwardly to the position shown in Fig. 8 in which the rays oflight do not pass through it.

The shutter of the camera, best shown in Figs. 4 to 7 inclusive, is ofthe fiap type, and comprises a cross shaft II5 rotatably mounted in thecasing, to which is secured the flap I I5 preferably of light material,such as aluminum. Theshaft I I5 also carries an arm I II which isarranged to contact with a limiting stop II 8 of slightly resilientmaterial, such as felt or rubber held in a bracket H9 secured to thewall of the casing 52, to limit the oscillation of the shaft H5 in acounter-clockwise direction when viewed as in Fig. 5. This arm I" servesalso as an operating arm, being engaged on its lower side by theoperating plunger or rod I20, the lower end of which, as shown in Fig.4, is operatively connectedto the forward end of an arm I2I, the rearend of which is pivoted at I22 to the side of the main casing 50. Aspring I23 urges the arm I2I upwardly to lift the plunger I20 tooscillate the shaft H5 to move the shutter flap II6 to the closedposition illustrated in Fig. 5. A cam I24, however, best shown in Fig.4, and operated as hereafter described, is effective upon a followerroller I25 on the arm I2I to depress this arm and the plunger I20 andthus to allow the shutter flap II6 to drop by gravity from the closedposition shown in Fig. 5 to the open position shown in Figs. 4 and 7.The arm I2I has upward extensions I26 at each side of the followerroller I25 which lie on each side of the cam I24 and thus limit lateralplay of the arm I2I.

For illuminating the articles to be copied suitable illuminating meansis provided, as best shown in Figs. 1 and 3. At the front of the machineare a pair of brackets I33 each in the form of a substantially verticalplate having a rounded top and each having secured thereto a pin I3Iadapted to fit loosely into a receiving socket I32 on the front of thecamera casing 52. Each of these brackets I33 carries a socket forreceiving an electric light bulb I33. Over each bulb is placed a quicklyremovable protecting and reflecting casing I34 enveloping the bulb I33at the top and front, but being open at the bottomso that light mayissue through the bottom opening. Each bracket I33 is provided with anupper pin I35 passing through a hole near the top of the casing I34, andwith a pair of lower pins I33 received in slots at the bottom of casingI34, so that merely by lifting the casing upwardly it may be disengagedand removed from the bracket I33 to permit access to the bulb I33 forreplacement thereof. Similarly, after the bulb has been replaced, thecasing 134 may be readily attached again simply by lowering it so thatthe pins I35 and I33 may be received in their respective hole and slots.The axis of each reflecting and protecting casing I34 is slightlyinclined as illustrated in the drawings so that the light furnished bythe illuminating units will be directed upon the article to bephotographed, diagrammatically illustrated at I31 in Fig. 8.

The driving mechanism for the parts so far described will now beexplained, first referring to Figs. 2 and 3. A suitable source of power,preferably an electric motor I43, is mounted near the front end of a bedplate I H, which is preferably of somewhat triangular shape in plan,having a three point support so that it may be readily adjusted andalined. The front or wide end of the bed plate I is supported on twoballs I42 and held down in contact with them by bolts I43, while therear or narrow end of. the bed plate is supported by the stud I44 andmay be adjusted upwardly or downwardly by shifting the nuts I45 and I43,

On this bed plate near the rear end thereof is mounted a worm reductiongear unit I41 driven directly from the motor I 43, as shown in Fig. 3,while this reduction gear I41 drives through a chain I43 or othersuitable drive, a shaft I43. 7

At its left hand end this shaft I43 carries a feeding cam I53, theoperation of which will be hereafter described. The shaft also carries aspur gear I5I, best seen in Fig. 9, meshing with another spur gear I52on a shaft I53 carrying a bevel gear I54 driving another bevel gear I55on a shaft I53 at right angles to the shafts I43 and I53. The shaft I53thus driven from the shaft I43 carries a sprocket I51 over which runs achain I53, Fig. 1, for driving the conveying mechanism which will behereafter described.

The shaft I43 also carries a pulley I33 (Figs. 2- and 9) insubstantially the same plane as the pulley 33 of the rewinding reel 35.A suitable friction drive, such as the coiled spring belt I3I, passesover the pulleys I33 and 33, so that rotation of the pulley I33 tends tobe transmitted to the rewinding pulley 33, but the coiled spring I3I mayeasily slip over the pulleys whenever the sensitized material isstationary and impedes the rotation of the rewinding reel 35.

The feeding of the sensitized material after each exposure is controlledby the cam I33 above mentioned. Referring now to Figs-3 and 10, it willbe seen'that this cam I53 acts upon a follower roll I13 mounted on ablock "I adjustable radially along an arm I 12 fixed to a shaft I13. Alag screw I14 threaded into the arm I12 passes through a slot in theblock I1I so that when the screw is loosened the block may be adjustedradially along the arm I12 toward and away from the shaft I13 and whenthe screw I 14 is tightened the block I1I will be held in adjustedposition. An adjusting screw I15 is provided for accurately adjustingthe block I1I along the arm.

By this arrangement, the effective distance of the follower roller I13from the axis of the shaft I13 can be adjusted through a limited rangeand thus the extent of oscillation of the shaft I13 at each actuation bythe cam I53'can be varied slightly, in order to adjust accurately theamount of feeding imparted to the sensitized material at each cycle ofoperation.

As best shown in Figs. 9 and 11, the shaft I13 is provided with a springI11 coiled around the shaft, one end of the spring being fixed to acollar I13 on the shaft and the other end of the spring engaging astationary part of the framework, so that the spring tends to rotate theshaft in a clockwise direction when viewed as in Figs. Band 10, and thusholds the follower roller I13 downwardly in engagement with the cam I53,but nevertheless permits the shaft I13 to be oscillated in acounter-clockwise direction by the action of the cam upon the followerroller. This counter-clockwise oscillation is transmitted through aone-way driving clutch I 13 (Figs. 11 and 12) to the gear I83 rotatablymounted on the shaft I13. The clutch is of any suitable oneway drivingconstruction, comprising, for example, a hub member I3I fixed to thegear I33 which is to be driven, and having a plurality of rollers I32mounted in tapered notches and pressed by springs I33 so as to engagethe internal face of ,a ring I34 fixed in the housing of the clutch I13.Thus any counter-clockwise rotation of the ring I34 which is fixed torotate with the shaft I13 is transmitted to the hub I3I and causescorresponding counter-clockwise rotation of the gear I33, but when theshaft I13 .returns in a clockwise direction under the influence of thespring I 11, then the rollers I32 will simply move slightly against theaction of their springs I33 so that the clutch slips without causingcorresponding movement of the gear I 33.

To prevent any accidental retrograde movement of the gear I33 it isprovided with a second clutch I35 similar in construction to the clutchI13, but the casing of which is non-rotatably secured to the frame workof the mechanism. By means of similar spring pressed rollers in knownmanner the clutch I35 will permit the gear I 33 to move in acounter-clockwise direction under the influence of the shaft I13, butwill positively hold it against accidental reverse movement.

Through the mechanism above described, each rotation of the shaft I43and its feeding cam I53 results in a single oscillation of the shaftI13, first in a counterclockwise direction as the follower roller I13moves up from the low point tothe high point of the cam, and then in aclockwise direction as the follower roller moves down from the highpoint to the low point. This oscillation of the shaft I13 is thustranslated into an intermittent unidirectional movement of the gear I33,which moves in a counter-clockwise direction when the'shaft is moving inthat direction, and which remains stationary when the shaft moves in areverse direction.

The gear I33, as best shown in Figs. 3 and 9,

meshes with a gear I33 on the shaft 14 which carries the feeding roller12. The shaft 14 in turn carries a spur gear I9I (Fig.9) meshing with aspur gear I92 on the shaft 15 of the other feeding roller 13. The gearsI9I and I92 are of the same proportion relative to each other as thediameters of the feeding rollers 12 and 13, so that these two rollerswill always rotate in synchronism. The gears I80 and I90 are soproportioned relative to each other that each intermittent movement ofthe-gear I80 will be suflicient to rotate the gear I90; enough to movethe feed rollers to a sufficient extent so that the exposed portion ofsensitized material is completely moved out of the exposure area and afresh unexposed portion is drawn into the exposure area of the focalplane. As before stated, the extent of feeding can be minutely adjustedby moving the .block I1I on which the follower roller I10 is mounted.

The cam I24 for operating the shutter of the camera is likewise mountedon the shaft I49 above mentioned, on which the feeding cam I50 ismounted. These two cams are so placed relative to each other on theshaft I49, that the feeding of the sensitized material will take placeonly when the shutter is closed, and the shutter will open only when thefeed rollers are at rest so that a fresh supply of sensitized materialis held stationary in the focal plane.

As previously stated, the present machine is provided with conveyormeans within the easing 53 for automatically positioning articles to bephotographed in proper position in the photographic field of the camera.This conveyor means is fully disclosed in the above mentioned co-pendingapplication Serial No. 582,361, of which this case is a division. Someof the features of the conveyor means may be briefly described inthepresent application, however, with reference to Figs. 1 and 3.

Near each end of the conveyor casing 53 is a cross shaft, the one nearthe left hand end being designated by the numeral 200 and the one nearthe right hand end being shown at 20I. Each shaft carries a pair ofsprockets 202, all of which may be identical in construction. Over thesesprockets runs a pair of conveyor chains having slats extendingtransversely from one chain to the other to provide a bed on which thecopy to be reproduced is placed. This copy may consist, for example, ofindex cards or any other desired articles or documents.

The conveyor is driven by any suitable means, preferably from the chainI58, which is driven from the sprocket I51. This chain I58, as shown inFig. 1, drives a sprocket 238 on a shaft in a leftward extension 241 ofthe conveyor housing 53, which extension contains a suitable form ofmechanism for driving the conveyor rightwardly through intermittent stepby step movements to carry successive pieces of copy into thephotographic field of the camera, all as described in the aforesaidce-pending application. The details of the conveyor means and of thedriving mechanism forming part of these means, do not a knob eacharticle on the conveyor will be held in the photographic field of thecamera during wardly by adjusting screws 351.

one, two, three, or four exposure operations of the camera as may bedesired.

After the exposure or exposures of each piece of copy have been made,further rightward movement of the conveyor eventually discharges thepiece of copy from the conveyor into a receiver 302 into which it isguided by a part 340, both mounted by means of a bracket 350 on theright hand end of the conveyor housing 53.

The conveyor housing 53 together with the extension 241 and the copyreceiver 302 are adjustably mounted as a unit relative to the maincasing parts 50 and 5| for focusing the camera. Preferably the conveyorcasing 53 is carried by vertical brackets 355 (Fig. l) secured to theends of the casing 5I by bolts 356 passing through slots in the bracketsso that when the bolts are loosened the brackets may be adjustedupwardly or down- The brackets 355, in turn, are secured to the conveyorcasing 53 by lag screws 350 which pass through relatively large holes inthe brackets and screw into the bottom of the conveyor casing. Whenthese screws 360 are loosened, the conveyor casing may be adjustedthrough a limitedextent both forwardly or backwardly or sideways, as maybe desired. Adjusting screws 35I are provided for assisting the forwardand backward adjustment of the conveyor.

In focusing the camera either initially at the factory or when settingup the mechanism at a place where it is to be used, the roll box 55 isremoved through the rear door 51, as previously explained, so that theoperator may see the image upon the ground glass plate 63. By means ofthe adjustments described immediately above, the conveyor and itsdriving mechanism and stacking mechanism can all be adjusted together asa unit, vertical adjustment being made, if necessary, to bring thearticles on the conveyor accurately into proper focus, while horizontaladjustment may be made so that when the conveyor is in its position ofrest, an article held by the holding means on the conveyor will beaccurately cen- Y of sensitized material is led from the roll 59forwardly, over the guide roll 50, and shoved downwardly through thespace between the focal plane support 83 (the glass plate) and theretaining plate 65. If desired, the retaining plate 65 may be removed,the sheet material may be laid against the front of the glass plate, andthe plate 65 may th:n be replaced by sliding it downwardly 'in itsguiding grooves.

The release lever 80 for the feed rollers is then oscillated to separatethe rollers 12 and 13 slightly from each other, after which the strip ofsensitized material is shoved on downwardly between these rollers andpulled downwardly and connected to the rewinding reel 85 in a mannerfamiliar to those skilled in the art. The handle 80 is then returned toits normal position, permitting the roller 13 to be pulled toward theroller 12 by the action of the spring18 so that the feeding rollerseffectively grip the sensitized material and will be operative to feedit upon rotation of the rollers. The various doors of the camera casingare then closed.

The camera is now ready for the actual taking of exposures. The motorand the illuminating lamps are turned on, and the operator, standing infront of and facing the machine, a little to the left of the cameralens, deposits the cards or other articles to be photographed on thecon-. veyor, one at a time, placing them accurately between certainholding lugs or guides provided on the conveyor so that they arepositioned in predetermined relation to the conveyor.

It will be recalled that the conveyor is driven intermittently. Duringone of its periods of rest one of the articles will be properlypositioned immediately below the camera prism in the photographic fieldof the camera. At this time the cam I24 (Fig. 4) on the shaft I49rotates to such a position that the follower roller I25 is forceddownwardly, depressing the lever I2I and the plunger I20, and permittingthe shutter H6 to drop by gravity to the open position shown in Fig. 4.Continued rotation of the shaft I49 brings the low point of the cam I24over the follower roller I25, so that the spring I23 moves the lever I2Iand the plunger I20 upwardly, thus shifting the shutter IIB from itsopen position to the closed position shown in Fig. 5, which completelyobstructs the light which would otherwise pass through the aperture 60in the masking plate 65 and reach the sensitized material.

After the shutter is completely closed the rotation of the cam I50(Figs. 3 and 10) is effective to lift up the follower roller I10 andcause a counter-clockwise oscillation of the feeding lever I12, whichproduces a corresponding counterclockwise movement of the shaft I13.Through the one way clutch I19 this movement is tranmitted to the gearI80, while through the gear I90 meshing therewith it causes a rotationof the feeding rollers 12 and 13, which is effective to feed thesensitized sheet material so as to remove the exposed portion from theexposure area of the focal plane, and draw a fresh unexposed portion ofthe material into the exposure area ready for the next exposure.

While this feeding-of the sensitized materialis taking place, andassuming that the mechanism is set for taking only one exposure of eacharticle, the conveyor is driven one step forwardly to bring a freshpiece of copy into the photographic field of the camera. At or after thecompletion of the conveyor movement and the feeding of the sensitizedmaterial, the cam I24 once more opens the shutter so that anotherexposure is made. Then when the shutter closes, the sensitized materialis once more fed downwardly and the exposed portion is graduallyaccumulated on the rewinding reel 85. Likewise the conveyor once moremoves forwardly to carry the photographed article cut of the field ofthe camera and to bring another article into the field.

If it is desired to take more than one exposure of each article, thecamera parts operate as before, but by shifting the control knob 251 theconveyor driving mechanism can be made to drive the conveyor forwardlyonly once for each two, three, or four exposures, so that the same pieceof copy remains in the photographic field of the camera for the desirednumber of exposures.

After the articles have been photographed, continued rightward movementof the conveyor discharges them into the receiver 302 where they arestacked for convenient removal.

When the supply of sensitized material on the roll 59 is exhausted, afresh roll is placed in the roll box 50 and the sensitized material isonce more threaded across the focal plane support, between the feedingrollers, and to a fresh rewinding reel 85. The full rewinding reel onwhich the exposed sensitized material has accumulated is removed fromthe apparatus by pulling outwardly on the handle 92 (Fig. 2) to releasethe reel from its supporting bearings, after which the exposed materialmay be developed or otherwise treated in any desired or suitable manner.

While one embodiment of the invention has been disclosed, it is to beunderstood that the inventive idea may be carried out in a number ofways.
